Venting Furnace With Pvc

Other aspects of high efficiency furnace venting.

Venting furnace with pvc.

You need to make sure your furnace is venting properly. Connect this furnace to an approved vent system only as specified in the venting requirements section of these instructions. The pvc pipes are used for air intake exhaust gas and to remove the corrosive condensation resulting from the combustion process. When the vent is withdrawing air from the house it expels the gas outside through the vent.

This structure generally uses the furnace vent pipe through roofbecause the b venting pipe is designed in vertical manner. Basic instructions on how to run pvc flue venting on high efficiency furnaces. Gas appliance direct vent clearances distances from direct gas vent to building features sidewall vent direct vent direct exhaust systems for gas fired heaters water heaters other appliances. The flue is also a safeguard against fire.

Combustion products must be discharged outdoors. Also known as the type b this vent is operating on the natural air convection. Read the manufacturer s instructions. To combat this issue a high efficiency condensing furnace uses pvc pipes to extract the acidic water from your home.

These pvc pipes are connected to the furnace and expelled outside. The venting system is installed at the same time as your high efficiency furnace. That way should there be a problem with the furnace that causes the exhaust temperature to exceed design the exhaust vent system has almost 40 more capacity to handle the excess heat before it reaches the point where it can fail. The furnace space as specified in the venting requirements section of these instructions.

Adequate clearance must be provided around the vent air intake terminals. A prime example would be the vent flange on new carrier bryant payne furnaces. These particular types of furnaces use positive pressure vent systems exhaust gas temperature less than 1400f above the dew point temperature and are always equipped with an induced draft motor that removes exhaust gases from the appliance and discharges them to the exterior. The vent pipe or flue is a vital component of the furnace that transmits emissions from the combustion process out of the building.

Table illustrations of the required space between a direct or side wall vent for a gas fired heating appliance and building windows doors corners gas meter air intakes sidewalks balconies. This high efficiency venting system must be installed when you install the new furnace. Despite the confusion the safe practice would suggest the use of pvc schedule 40 pipes for the air intake vent on the furnace and cpvc for the exhaust flue vent given its higher service temperature. These are connected to the furnace and routed out to the side of your home.
